CEP: Spotlight on Safety - LOPA — A Valuable Risk-Reduction Tool

November
2012
Spotlight on Safety
John F. Murphy, P.E.
Layer of protection analysis (LOPA) is a simplified process risk-assessment technique that uses order-of-magnitude estimates for initiating events, consequence severity, and likelihood of failure of independent protection layers (IPLs) to approximate the risk of a scenario. It is generally used after a process hazard analysis (PHA) team has identified a hazard scenario that requires further analysis to ensure the adequacy of the safeguards that exist or are being proposed.

CEP: Editorial - On the Path to Sustainability

July
2012
Editorial
Cynthia F. Mascone
I love soaking up nature — whether I’m hiking over the red rocks of Sedona, strolling along Jones Beach as the waves of the Atlantic Ocean roll in, taking shelter indoors as an angry thunderstorm rages outside, stargazing miles from the nearest town … or just sitting on my porch watching the grass in my tiny New York City yard grow. Whatever the activity, I continue to be amazed at the awesomeness of the world we live in. Yet I wonder what the planet will be like for our children. Will nature still be as wonderful for them as it is for me?

CEP: Editorial - Alternative Paths to Sustainability

October
2012
Editorial
Cynthia Mascone
When I wrote last month’s editorial about my trip down the path to sustainability, I intended it to be the third article of three (“On the Path to Sustainability” in July, “AIChE’s Path to Sustainability” in August, and “A ChE’s Path to Sustainability” in September). My journey began while I was on vacation in Arizona at the beginning of the summer. Unexpectedly, I experienced sustainability from a different angle during my annual end-of-summer staycation. Thus, this fourth article on sustainability — in sports.
